End Taxpayer Funding of Gender Experimentation Act of 2025

This bill prohibits federal funds from covering gender transition procedures in any federal health program, including Medicaid, military health care, and federal employee benefits. It broadly defines "gender transition procedures" to include hormone treatments, surgeries (like hysterectomies or breast implants), and cosmetic procedures, while excluding treatment for disorders of sex development, medical emergencies, or precocious puberty. The bill also modifies the Affordable Care Act to block federal premium tax credits and cost-sharing subsidies for health plans covering these procedures, though it allows states or individuals to pay for separate coverage using non-federal funds. It directly affects federal health programs, Medicaid, and ACA marketplace plans by restricting federal funding for gender transition care.
